WILLIAM H. HANKINSON, OF NEW YORK, N. Y.

DUST-COLLECTOR.

SPECIFICATION forming part of Letters Patent No. 507,319, dated October24, i893. Application iiled August 31, 1892. Serial No. 444,627. (Nomodel.)

To all whom it may concern:

Be it known that I, WILLIAM H. HANKINSON, a citizen of the UnitedStates, and a resident of the city, county, and State of New York, haveinvented certain new and useful Improvements in Dust-Collectors, ofwhich the following is a specification, reference being had to theaccompanying drawings, forming part thereof.

My invention relates to improvements in dust collectors or separators.`

The main object of my invention is to collect the dust arising orproceeding from carpet beating and cleaning establishments, andprecipitate it, so as to avoid the-pollution of the atmosphere.

Another object of my invention is to accomplish this result with aminimum amount of water.

With these objects in view, my invention consists in such features ofconstruction and combination of parts as will first be described inconnection with the accompanying drawings and then pointed out in theclaims.

In the drawings-Figure 1 is a side elevat1on,partlyinsection,illustrating a plant ern- Fig. 2 is a detail, vertical sectionalview, partly in elevation, of the first reservoir. Fig. 3 is a similarview of the second reservoir. Fig. 4: is a top, plan view of the secondreservoir. Fig. 5 is a similar view of the supply tank and strainers.Fig. 6 is a d etail, sectional view of Fig. 5, taken on the line 66mm,looking in the direction of the arrows.

Referring to the drawings, a is a flue leading from the exhaust fan orother device Which removes the dust-laden air from the carpetcleaning orother machines and forces it through the iiue, a, to a dust-reservoir,b, preferably situated partly below and partly above the roof of thebuilding. In this reservoir, h, is located the upper end `of awater-supply pipe, n, having a sprayer, c, at its upper end. The upperend of the dust-reservoir, b, communicates with a second reservoir, g,by means of a pipe, e, preferably bent as shown, and opening into thereservoir, g, at a short distance above its bottom. lAround the pipe, e,is a spray-pipe, f in communication with the pipe, n, through a pipe, o.The bottom of resof the upper screen. The lower ends of the screens arearranged to deliver the tailings or overflow into compartment, r', whichcompartment is connected with the sewer by an outlet pipe, q, anoverflow pipe, s, also being provided. An inlet pipe having a faucet, Z,supplies water from any suitable sources when desired, while a pump, m,pumps the clear Water from compartment, k, through pipe, p, to thereservoirs, b, and g, through pipes, fa, and o.

The operation of my apparatus, briefly stated, is as follows: Thedust-laden air from the carpet-cleaning or other machines isforcedthrough the flue, a, to reservoir, b,where it is compelled to ascend andpass through a spray of water, issuing from the sprayer, c, the dustthereby becoming moistened, thus being rendered much heavier so that alarge proportion of it drops down into the lower part, d, of thereservoir, b. Theair, with that part of the dust which is precipitated,is forced through pipe, e, into reservoir, g, when it emerges from thepipe and turns upward,being then met by the spray, f, which removes theremaining dust and causes it to fall to the bottom of reservoir, g, thepurified air escaping through the top of the reservoir, this escapebeing regulated as desired,by means of the doors or lids, u. The spray,f, together with the dust which falls in the bottom of reservoir, g, iscarried through pipe, h, to the bottom, d, of reservoir, h, thereuniting with the dust first precipitated, and With the water fromsprayer, c. From here, the dust-laden water flows through pipe, t', tothe screens, j, which strain the dust from the water and allows theclean water to pass into compartment, k, from whence it is pumped to thesprayers, f,and c, to be used over again. Thedust, together with a smallICO percentage of watei-,is carried from the screens into thecompartment, fr, when it is conducted to the sewer through pipe, q, orcarried olf by pipe, s, in case of an overflow.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with a primary and a secondary dust receiver, and afine connecting both receivers, of a circular sprayer snrronnding thelower end of the flue and located within the secondary dust receiver,substantially as set forth.

2. The combination, with a primary and a secondary dust receiver, a iineconnecting both receivers and a sprayer for each receiver, of a pipeconnecting the bottom of the secondary receiver to the bottom of theprimary receiver, substantially as set forth.

`with two compartments, and an inclined sieve above one of thecompartments and having its lower end opening over the othercompartment, substantially as set forth.
